6 Claims. (01. 14092.1)

The present invention relates to improvements in a form for shaping concrete post reinforcements and this application constitutes a division of an application for improvements in reinforcements for concrete posts and method of making same filed February 26,1936, Serial #65386.

One of the objectsof the present invention is the provision of a form through the medium of which reinforcements for concrete :fence posts and the like may be fabricated. v 1

A further object of the invention is the provision of a single piece of material so constructed and arranged that the reinforcement may be readily released from the form after fabrication of the reinforcement has been accomplished.

A further object of the invention is the provision of novel detachable reinforcement holding means in the form.

A still further object of the invention is the provision of recessed means through the medium of which the reinforcement maybe readily and properly shaped during the 'fabrication of the reinforcement means.

The invention will be fully understood from the following description and claims when read in connection with the drawing accompanying and forming a part of this specification in which:

Figure 1 is a perspective view illustrating my novel reinforcement form and illustrating the detachable holding elements thereof. The said view further illustrates the concavo-convex longitudinal corners of the form and the U-shaped portion of said form.

Figure 2 is an end elevational view of my device illustrating one of the detachable holding devices arranged therein.

Figure 3 is a view similar to Figure 2 and showing the reticulated material post reinforcement arranged thereon.

Figure 4 illustrates the reticulated reinforcement after it has been produced ready for use and in this view I have illustrated the reinforcement with the ends of the longitudinal irons bent upwardly and inwardly.

Figure 5 is an elevational view of my novel reticulated reinforcement per se spread out.

Similar numerals of reference designate corresponding parts in all of the views of the drawmg.

Referring to the drawing, my novel device is illustrated as a whole by the numeral 5, and it comprises a single piece of bendable material indicated by the numeral 6, and particular attention is invited to the fact that in construction of the form I taper same longitudinally, and

this for the purpose of permitting a reinforcement element to be produced with a tapered configuration asit is the usual practice in producing concrete posts or the like to taper said post longia tudinally. I wish to have it understood that the 5 form mayj be molded into the shape illustrated in Figure 1 and of any suitable metal.

1 The form 5 is of a continuous pieceof material or of molded material, and it is provided with a Ushaped portion 1 that produces the lips 8 10 and 9 respectively. Provided, preferably equidistantly throughout the form 5 are apertures and particular. attention is invited to the fact that the apertures are so arrangedin the upper Wall l0 and the lower wall II, and the lips 8 and 9, so that allof these apertures are in direct registration with each other. A throat I2 is provided between the lips 8 and 9 for an important purpose hereinafter specifically referred to.

Adapted to enter the apertures of the form 5 and entirely piercing said form are pins I3, and the purpose of these pins will be apparent in the description of the mode of use of my novel device. I now' invite particular attention to a very salientfeature of my device which consists of providing concavo-convex grooves l4 longitudinally throughout the corners or edges of the form.

In the practical operation of my device when it is desired to form a reinforcement for concrete posts and the like it is simply necessary'to bend a piece of reticulated reinforcement material around the form 5 and in the initial operation of forming the reticulated material, the pins 13 are removed from the form 5 and one end of the reinforcement material is placed into the throat l2 of the form 5. The pins l3 are then dropped into the apertures of the form and the reticulated material bent about the form 5 and thus, the bending operation may be accomplished 40 without liability of the reticulated material pulling away from the form and this for the reason that the pins I 3 look the reticulated material within the throat I2 of the form. At this point I wish to invite attention to the fact that some of the longitudinal rods of the reticulated material will enter and rest in the longitudinal concavo-convex grooves M of the form during the bending operation and consequently a proper concrete post reinforcement is produced, and one that will conform readily to the configuration of a contemplated concrete post. Manifestly the free end of the reticulated material is bent upon the form and then looped about one of the transverse rods of the reinforcing element, all of which because of its extremely simple construction, the

production of reinforcement elements for concrete posts and thelike may be carried put without the employment of skilled or highly specialized labor and naturally the few elements of construction of the form notonly evidence the small amount of money involved in the production of the form, but likewise eliminates all future expense during the practice of the device.

What I o1aimis: 1. A form by which a reinforcement element may be produced and comprising a single piece of bendable material, so constructed and arranged,

' whereby a throat is provided and confined within the upper and lower walls thereofj' said upper and lower walls andth'e walls that form the throat having registering apertures therein, and means adapted to pierce the walls and be confined within the walls in a removable manner.

2. A form for producing reinforcement elements for concrete posts and the like and com prisingjra' single piece of bendable material tapered throughout the longitudinal area thereof, and so constructed and arranged that a throat is formed and confinedwithin the form, said form having apertures provided therein and adapted to register with each other, means adapted to enter the apertures and removably arranged therein, and concavo-convex grooves formed on the form.

3. A device for the purpose specified, comprising a single piece of bendable material and having a throat produced therein, said form being tapered longitudinally and having a series of apertures positioned throughout the longitudinal length of the form and in registration with the walls that produce the throat, means adapted to pierce the form and removably engaged within the apertures and longitudinal concave-convex grooves arranged at the corners of the form.

4. A form for-the purpose specified, having a throat produced therein, grooves formed at the corners of the form, said form having apertures provided throughout the longitudinal length of the form and in registration with the walls that produce the throat, pins adapted to be removably confined within the apertures and means arranged in the form whereby the longitudinal rods of a reinforcing element will enter said grooves during the fabrication of the reinforcing elements.

5. A form for use in the construction'of a concrete post reinforcing element and comprising a single piece of material so constructed and arranged that a throat is provided between the upper and lower walls of the form and extending longitudinally in oneside wall of the form,,said throat having the walls thereof lying in a plane similar to the upper and lower walls of the form and resting within said walls; all of said walls having registering apertures therein, pins adapted to pierce allof the walls and arranged removably in'the apertures and grooves formed at the corners of the form, substantially as and for the purpose specified.

6. A form for producing concrete post reinforcing elements comprising a single piece of material tapered throughout the longitudinal area thereof, grooves formed at .the corners of the form, a throat within said form, said form and throat having apertures therein and in register,

, removable means adapted for engagement with the apertures and means arranged in the form wherebythe longitudinal rods of the reinforcing element will enter said grooves during the fabrication of the reinforcing elements.
